From early 15c. as "power that rules destinies, agency which predetermines events; supernatural predetermination;" also "destiny personified." Meaning "that which must be" is from 1660s; sense of "final event" is from 1768. The Latin sense evolution is from "sentence of the Gods" (Greek theosphaton) to "lot, portion" (Greek moira, personified as a goddess in Homer). The sense "one of the three goddesses (Clotho, Lachesis, and Atropos) who determined the course of a human life" is in English by 1580s. Often in a bad sense in Latin: "bad luck, ill fortune; mishap, ruin; a pest or plague." The native word in English was wyrd (see weird).
